[hai shi]

New submission from hai shi <shihai1991 at 126.com>:

some typeobject using `tp_vectorcall_offset`, if we use `PyType_FromModuleAndSpec` to create the the typeobject, it will be faild due to `PyType_FromModuleAndSpec` lack the process of `tp_vectorcall_offset`.

so we should adding some process  like https://github.com/python/cpython/blob/master/Objects/typeobject.c#L2966-L2976.
